Elastic cloud video editing and multimedia search

ABSTRACT

Technologies for cloud-based media search and editing include a video editor configured to build a media query and associate the media query with a dynamic content slot of a media program. When generating video output based on the media program, the video editor transmits the media query to a cloud analytics server and receives search results identifying one or more media clips produced by a number of mobile computing devices. The video editor may display a list of clips for selection by the user or may automatically include one of the clips in the output. The cloud analytics server transmits an acceptance policy defining criteria for acceptable media, based on the media query, to the mobile computing devices. The mobile computing devices configure capture settings according to the acceptance policy and may display a user interface to assist the user in capturing acceptable media. Other embodiments are described and claimed.

BACKGROUND

Video production is typically laborious and time-consuming. When assembling a video program from a collection of video clips, a video producer must organize a large number of video clips, evaluate each video clip for content, and arrange the selected video clips as desired. Particularly for live video production, typical systems require large numbers of human operators to incorporate large numbers of cameras or video sources into a single video production.

Cloud computing services allow for data processing and storage distributed over a ubiquitous network such as the Internet. Cloud computing may be scalable to grow or shrink available computing and storage resources according to current demand. Cloud computing services may collect and distribute content produced by numerous mobile devices with persistent network connections. Such “crowd-sourced” content may provide numerous unique, individualized views of the same event.

Referring now to FIG. 1, in one embodiment, a system 100 for cloud-enabled multimedia search and video editing includes a video editor 102, a cloud analytics server 104, and a number of mobile computing devices 106, all in communication with each other over a network 108. In use, as discussed in more detail below, the mobile computing devices 106 capture media data such as video clips, audio clips, or still images, and upload the media data to the cloud analytics server 104. The cloud analytics server 104 processes the uploaded media data, producing a searchable database of media data and related metadata. The video editor 102 edits a media program including one or more dynamic content slots. The video editor 102 builds a media query associated with each dynamic content slot and submits the media queries to the cloud analytics server 104. The media queries may include search terms based on media content and metadata, or may be based on similarity to a given sample media clip as discussed in more detail below. The video editor 102 receives search results from the cloud analytics server 104 and inserts the search results into the associated dynamic content slot when generating video output. Thus, the video editor 102 may allow for near-real-time search and incorporation of cloud-based media into a video production. Although illustrated as including one video editor 102, in some embodiments the system 100 may include any number of video editors 102 that may produce independent video output (i.e., a many-to-many-to-many relationship).

The disclosed technologies may allow a video producer to incorporate crowd-sourced content into a video production without requiring cost-prohibitive or overwhelming manual review of submitted content. Incorporation of near-real-time crowd-sourced content into a video production may allow for inclusion of unique and diverse views of notable events that could otherwise go unnoticed. Those diverse views may increase the artistic, entertainment, and informative value of video productions.

The video editor 102 may be embodied as any type of computer device for performing the functions described herein. For example, the video editor 102 may be embodied as, without limitation, a computer, a desktop computer, a workstation, a laptop computer, a notebook computer, a tablet computer, a smartphone, a distributed computing system, a multiprocessor system, a consumer electronic device, and/or any other computing device configured to perform cloud-enabled video editing. As shown in FIG. 1, the video editor 102 includes a processor 120, an input/output subsystem 122, a memory 124, a data storage device 126, a communication circuit 128, and a display 130. Of course, the video editor 102 may include other or additional components, such as those commonly found in a computer workstation (e.g., various input/output devices), in other embodiments. Additionally, in some embodiments, one or more of the illustrative components may be incorporated in, or otherwise form a portion of, another component. For example, the memory 124, or portions thereof, may be incorporated in the processor 120 in some embodiments.

The processor 120 may be embodied as any type of processor capable of performing the functions described herein. For example, the processor 120 may be embodied as a single or multi-core processor(s), digital signal processor, microcontroller, or other processor or processing/controlling circuit. Similarly, the memory 124 may be embodied as any type of volatile or non-volatile memory or data storage capable of performing the functions described herein. In operation, the memory 124 may store various data and software used during operation of the video editor 102 such as operating systems, applications, programs, libraries, and drivers. The memory 124 is communicatively coupled to the processor 120 via the I/O subsystem 122, which may be embodied as circuitry and/or components to facilitate input/output operations with the processor 120, the memory 124, and other components of the video editor 102. For example, the I/O subsystem 122 may be embodied as, or otherwise include, memory controller hubs, input/output control hubs, firmware devices, communication links (i.e., point-to-point links, bus links, wires, cables, light guides, printed circuit board traces, etc.) and/or other components and subsystems to facilitate the input/output operations. In some embodiments, the I/O subsystem 122 may form a portion of a system-on-a-chip (SoC) and be incorporated, along with the processor 120, the memory 124, and other components of the video editor 102, on a single integrated circuit chip.

The data storage device 126 may be embodied as any type of device or devices configured for short-term or long-term storage of data such as, for example, memory devices and circuits, memory cards, hard disk drives, solid-state drives, or other data storage devices. The data storage device 126 may store, permanently or temporarily, media data received from the cloud analytics server 104 in response to media queries.

The communication circuit 128 of the video editor 102 may be embodied as any communication circuit, device, or collection thereof, capable of enabling communications between the video editor 102, the cloud analytics server 104, and/or other remote devices. The communication circuit 128 may be configured to use any one or more communication technology (e.g., wireless or wired communications) and associated protocols (e.g., Ethernet, Bluetooth®, Wi-Fi®, WiMAX, etc.) to effect such communication.

The display 130 of the video editor 102 may be embodied as any type of display capable of displaying digital information such as a liquid crystal display (LCD), a light emitting diode (LED), a plasma display, a cathode ray tube (CRT), or other type of display device. In some embodiments, the display 130 may be coupled with a touch screen to facilitate user interaction.

The cloud analytics server 104 is configured to provide services including sorting and processing media data uploaded by the mobile computing devices 106. The cloud analytics server 104 may be embodied as any type of server computing device, or collection of devices, capable of performing the functions described herein. As such, the cloud analytics server 104 may be embodied as a single server computing device or a collection of servers and associated devices. For example, in some embodiments, the cloud analytics server 104 may be embodied as a “virtual server” formed from multiple computing devices distributed across the network 108 and operating in a public or private cloud. Accordingly, although the cloud analytics server 104 is illustrated in FIG. 1 and described below as embodied as a single server computing device, it should be appreciated that the video editor 102 may be embodied as multiple devices cooperating together to facilitate the functionality described below.

The cloud analytics server 104 includes compute resources 140 and storage resources 142 that may be used to process and search media data. The compute resources 140 may be embodied as physical processors, servers, virtual machines, or any other physical or virtual computing resource capable of performing the functions described herein. The cloud analytics server 104 may allocate or de-allocate compute resources 140 based on workload or other factors. The storage resources 142 may be embodied as physical storage devices, virtual disks, network servers, or any other form of data storage that may be used by the compute resources 140. In some embodiments, the storage resources 142 may be distributed among several geographical locations. Because the compute resources 140 and the storage resources 142 are scalable on demand, the cloud analytics server 104 may be known as an “elastic” cloud service provider.

The cloud analytics server 104 further includes media data 144 and metadata 146. The media data 144 is a repository for media data uploaded by the mobile computing devices 106. The metadata 146 is a repository for data related to the media data 144, for example, semantic data describing the content of the media data 144, location data associated with the media data 144, or technical information relating to the media data 144 such as the type of camera used to record the media data 144, quality information, file format information, or the like. Metadata 146 may be embedded in the media data 144, stored separately from the media data 144, or some combination of the two. The media data 144 and/or the metadata 146 may be stored using the storage resources 142 of the cloud analytics server 104, or may be stored in one or more data servers accessible by the cloud analytics server 104 over the network 108. As described above, in some embodiments, the media data 144 and/or the metadata 146 may be distributed across data servers located in multiple geographic locations.

Each of the mobile computing devices 106 is configured to capture media data and transmit the captured media data to the cloud analytics server 104. Each mobile computing device 106 may process captured media data prior to transmission to ensure the captured media data satisfies requirements of the video editor 102. Additionally, each mobile computing device 106 may include a user interface to assist a user in capturing media data desired by the video editor 102. Each mobile computing device 106 may be embodied as any type of mobile computing device capable of performing the functions described herein, including, without limitation, a computer, a smartphone, a tablet computer, a laptop computer, a notebook computer, a cellular telephone, a handset, a messaging device, a vehicle telematics device, a network appliance, a web appliance, a distributed computing system, a multiprocessor system, a processor-based system, and/or a consumer electronic device. Illustratively, a mobile computing device 106 includes a processor 160, an I/O subsystem 162, a memory 164, a data storage 166, a communication circuit 168, a display 170, and/or other components and devices commonly found in a smartphone or similar computing device. Those individual components of the mobile computing device 106 may be similar to the corresponding components of the video editor 102, the description of which is applicable to the corresponding components of the mobile computing device 106 and is not repeated herein so as not to obscure the present disclosure.

The mobile computing device 106 further includes a camera 172, a microphone 174, and location circuitry 176. The camera 172 may be embodied as a digital camera or other digital imaging device integrated with the mobile computing device 106. The camera 172 includes an electronic image sensor, such as an active-pixel sensor (APS), e.g., a complementary metal-oxide-semiconductor (CMOS) sensor, or a charge-coupled device (CCD). The camera 172 may be capable of capturing still images and/or video. The microphone 174 includes a transducer to capture audible sound waves as sound information on the mobile computing device 106. Instead of a microphone 174, in other embodiments, the mobile computing device 106 may include any sensor capable of capturing audio signals, such as a line input jack, an analog-to-digital converter (ADC), or other type of audio sensor. The microphone 174 may be capable of capturing standalone audio or, in conjunction with the camera 172, audio information for a video recording.

In the illustrative embodiment, the mobile computing device 106 includes location circuitry 176. The location circuitry 176 may be embodied as any type of sensor capable of determining the precise or approximate position of the mobile computing device 106. For example, the location circuitry 176 may be embodied as a global positioning system (“GPS”) receiver, capable of determining the precise coordinates of the mobile computing device 106. In other embodiments, the location circuitry 176 may triangulate the position of the mobile computing device 106 using distances or angles to cellular network towers with known positions, provided by the communication circuit 168. In other embodiments, the location circuitry 176 may determine the approximate position of the mobile computing device 106 based on association to wireless networks with known positions, using the communication circuit 168.

As discussed in more detail below, the video editor 102, the cloud analytics server 104, and the mobile computing devices 106 are configured to transmit and receive data with the other devices of the system 100 over the network 108. The network 108 may be embodied as any number of various wired and/or wireless networks. For example, the network 108 may be embodied as, or otherwise include, a wired or wireless local area network (LAN), a wired or wireless wide area network (WAN), and/or a publicly-accessible, global network such as the Internet. As such, the network 108 may include any number of additional devices, such as additional computers, routers, and switches, to facilitate communications among the devices of the system 100.

Referring now to FIG. 2, in one embodiment, the video editor 102 establishes an environment 200 during operation. The illustrative environment 200 includes a query builder module 202, a video editing module 206, and a video output module 208. The various modules of the environment 200 may be embodied as hardware, firmware, software, or a combination thereof.

The query builder module 202 is configured to build media queries based on selections received from a user of the video editor 102. Each media query may be used to dynamically search for media information stored and/or indexed by the cloud analytics server 104. Each media query may be embodied as a set of query parameters selected by the user, including metadata query parameters, media query parameters, and sample media query parameters, as described below. The media query may be submitted to the cloud analytics server 104 to be run immediately, or scheduled in advance to run at a later date and time. In some embodiments, those functions may be performed by sub-modules, for example, by a query scheduling module 204.

The video editing module 206 is configured to manage and edit a media program including dynamic content slots. The video editing module 206 may provide a timeline interface to the media program, allowing the user to lay out pre-programmed media and dynamic content slots. The video editing module 206 associates media queries built by the query builder module 202 with dynamic content slots of the media program.

The video output module 208 is configured to render the media program produced by the video editing module 206 into a video output in a suitable format. The video output may include a video data file, a video data stream, or a video stream suitable for live broadcast. The video output module 208 incorporates media data received from the cloud analytics server 104 in response to the media query into the video output at the associated dynamic content slot.

Referring now to FIG. 3, in one embodiment, the cloud analytics server 104 establishes an environment 300 during operation. The illustrative environment 300 includes an analysis module 302, a search module 304, and a resource scheduling module 306. The various modules of the environment 300 may be embodied as hardware, firmware, software, or a combination thereof.

The analysis module 302 is configured to receive media data 144 uploaded from the mobile computing devices 106 and analyze the media data 144 to allow for searching. The analysis module 302 may perform any analysis on the media data that may facilitate searching; for example, the analysis module 302 may perform facial detection, object detection, text recognition, color balance and saturation analysis, and audio tune analysis. The analysis module 302 may also evaluate the focus, stability, exposure, or lighting of the media data 144, determine whether the media data 144 includes audio, and evaluate image data for motion. The analysis module 302 may store the results of analysis in the metadata 146.

The search module 304 is configured to search the media data 144 based on a media query received from the video editor 102 and return the search results. As described above, the media query may be based on metadata query parameters, media query parameters, or sample media query parameters. The search module 304 may search against the media data 144, the metadata 146, or any combination of the two.

The resource scheduling module 306 is configured to schedule compute resources 140 and/or storage resources 142 based on requests received from the video editor 102. For example, the resource scheduling module 306 may pre-allocate compute resources 140 and/or storage resources 142 in anticipation of receiving a large amount of uploaded media data near the scheduled date of a media query. Similarly, the resource scheduling module 306 may pre-allocate compute resources 140 and/or storage resources 142 that are geographically close to the scheduled location of the media query. In some embodiments, the resource scheduling module 306 may schedule resources automatically based on the media query.

Referring now to FIG. 4, in one embodiment, each mobile computing device 106 establishes an environment 400 during operation. The illustrative environment 400 includes a media acquisition module 402 and in some embodiments may include a metadata module 410. The various modules of the environment 400 may be embodied as hardware, firmware, software, or a combination thereof.

The media acquisition module 402 is configured to capture media data 144 using sensors of the mobile computing device 106 such as the camera 172 and microphone 174. The media acquisition module 402 is further configured to upload captured media data 144 to the cloud analytics server 104. In some embodiments, the media acquisition module 402 may process the captured media data 144 prior to uploading, to ensure that an acceptance policy created by the video editor 102 has been satisfied. The media acquisition module 402 is further configured to present a user interface to facilitate capturing media data 144. The user interface may provide instructions or other assistance to ensure captured media data 144 satisfies the acceptance policy of the video editor 102. In some embodiments, those functions may be performed by sub-modules, for example, by a media capture module 404, a media upload module 406, or a user interface module 408.

In some embodiments, the metadata module 410 is configured to embed metadata 146 into the captured media data 144 prior to upload. The metadata 146 may include technical attributes of the mobile computing device 106 or its components such as the camera 172 or the microphone 174. The metadata 146 may include technical attributes of the captured media data 144, such as exposure, focus, aperture, or shutter settings. The metadata 146 may include location information, for example GPS coordinates provided by the location circuitry 176. In some embodiments, the metadata 146 may include information provided by other sensors of the mobile computing device 106, for example, information on altitude, motion, temperature, compass direction, or spatial orientation. Additionally, in some embodiments, the metadata 146 may include metadata entered by the user, for example tags, labels, or other annotations.

Referring now to FIG. 5, in use, the video editor 102 may execute a method 500 for cloud-enabled video editing. The method 500 begins with block 502, in which the video editor 102 builds a media query based on query parameters selected by the user of the video editor 102. The video editor 102 may present a user interface to allow the user to configure the media query. For example, referring to FIG. 6, diagram 600 illustrates one embodiment of a media query builder 602. The control groups 604, 606, 608 of the media query builder 602 illustrate potential query parameters that may be selected by the user.

Referring back to FIG. 5, in block 504, in some embodiments, the video editor 102 receives metadata-based query parameters from the user. Metadata-based query parameters may be used to search indexed description data of the metadata 146 that is related to the media data 144, but not necessarily embodied in the content of the media data 144. For example, as illustrated in control group 604 of FIG. 6, metadata-based queries may be based on search keywords, plaintext description, technical metadata attributes, a sentiment factor, location, or date and time. Search keywords and plaintext description may be associated manually with the media data 144, or may be associated through automated analysis by the cloud analytics server 104. Technical metadata attributes, for example white balance settings, frame rate, shutter settings, aperture settings, and the like, may be supplied by the mobile computing device 106 at the time of capture. The sentiment factor may be assigned algorithmically by the cloud analytics server 104 based on content analysis of the media data 144, or may be derived from public input. Location and date/time information may also be supplied by the mobile computing device 106 at the time of capture.

Referring back to FIG. 5, in block 506, in some embodiments, the video editor 102 receives content-based media query parameters from the user. Media query parameters may be used to search information derived through analysis of the media data 144 itself. Such analysis may be performed by the cloud analytics server 104 ahead of time, to improve search performance For example, as illustrated in control group 606 of FIG. 6, media queries may be based on focus, stability, lighting or exposure, audio, or motion. Focus and stability may be used to restrict the search to media clips that are in-focus and stable, that is, media clips captured without excessive camera shaking. Lighting and exposure may restrict the search to media clips captured under appropriate lighting conditions. As an example, audio may be used to return only media clips including an audio track. As another example, motion may be used to return only media clips with motion detected, for example media including physical gestures, media panning across a scene, or media including moving objects within a scene. As another example, media queries may be based on gestures detected within the media clips. Such media query parameters may be used by the video editor 102 to restrict the search to media clips having desirable quantities and to exclude media clips unsuitable for use in the output video.

In block 508 of the method 500 of FIG. 5, in some embodiments, the video editor 102 receives a sample media query parameter and associated matching options from the user. The sample media may be used to search for similar media clips given a stock media clip as a reference. The cloud analytics server 104 may process the sample media similarly to the media data 144, and use the processing results as a basis for comparison. For example, as illustrated in control group 608 of FIG. 6, sample media queries may include options to match media clips based on facial recognition, object recognition, text recognition, color balance, color saturation, or audio tune. The video editor 102 may supply a sample media clip including an image of a person's face, e.g., a celebrity or newsworthy individual. Facial recognition may search for media clips also including that person's face. Similarly, the sample media clip may include images of a particular object or written text that may be the basis for a search. Color balance and color saturation matching may be used to search for media clips containing similar color balance and/or color saturation. Matching colors may allow the resulting media clips to fit in well with the rest of the media program.

Referring back to FIG. 5, in block 510, in some embodiments, the video editor 102 may receive a scheduled date and/or location for the media query. As illustrated by control group 616 of FIG. 6, in some embodiments the user of the video editor 102 may schedule the search for a future time, or may submit the search immediately. The scheduled date and/or location may correspond to a future broadcast or live performance of the media program. As described below, the scheduled date may be used to coordinate the compute resources 140 and/or the storage resources 142 of the cloud analytics server 104. Additionally, in some embodiments, the location for the media query may be fine grained and may include orientation information, allowing selection of media from particular viewpoints of a large event. For example, the location may specify locations and viewing angles in a stadium used for a live sporting event. Thus, the media query may build a panoramic view of an event from multiple view points.

In block 512 of the method 500 of FIG. 5, after building the media query, the video editor 102 associates the media query with a dynamic content slot in the media program. The dynamic content slot represents a portion of the media program that will be replaced with dynamic content as the video output is generated. For example, referring to FIG. 7, diagram 700 illustrates a media program 702. The media program 702 includes three pre-programmed content segments 704, 708, 712. Dynamic content slots 706, 710 are positioned between the pre-programmed content segments 704, 708, 712. Each dynamic content slot 706, 710 has a duration and an associated media query. In a user interface of the video editor 102, each dynamic content slot 706, 710 may be represented with an icon derived from the media query, such as a thumbnail representation of a sample media clip. For example, when producing a news program on a hurricane, the content segment 704 may include a news anchor introduction. The dynamic content slot 706 may be associated with a media query based on the time and location of the hurricane, searching for severe weather and evacuation. Stock footage of a hurricane may be provided as a sample media clip. Content segment 708 may be a pre-recorded correspondent segment. Dynamic content slot 710 may include a media query based on the location of the hurricane, searching for themes of recovery and hope. Content segment 712 may include a news anchor conclusion.

Referring back to FIG. 5, in block 514, the video editor 102 transmits the media query to the cloud analytics server 104. As described above, the media query may be submitted for immediate evaluation and search, or may be submitted for evaluation and search at a scheduled time. In some embodiments, in block 516, the video editor 102 may request scheduling of cloud resources of the cloud analytics server 104 based on the scheduled query. For example, the user of the video editor 102 may anticipate a large number of media submissions associated with the date and location of a live event. Accordingly, the video editor 102 may request that the cloud analytics server 104 pre-allocate compute resources 140 to be available at the date or location of the scheduled query. In such example, the cloud analytics server 104 may prepare additional virtual machines on the date of the scheduled query, or move virtual machines to a cloud datacenter near the location of the scheduled query. Additionally, or alternatively, the video editor 102 may request the cloud analytics server 104 to pre-allocate storage resources 142 based on the date and location of the scheduled query. Scheduling of cloud resources may be requested based on a user selection, for example, the checkbox 614 of FIG. 6.

In some embodiments, in block 518 of the method 500 of FIG. 5, the video editor 102 may request that the query parameters of the media query be pushed by the cloud analytics server 104 to the mobile computing devices 106. Some or all of the query parameters may represent an acceptance policy of the video editor 102; that is, the video editor 102 may only accept media clips satisfying those query parameters. In such embodiments, the mobile computing devices 106 may apply the query parameters of the acceptance policy to captured media clips prior to uploading to the cloud analytics server 104. By applying query parameters before uploading media clips, the quality of uploaded media clips may be improved, and the processing required by the cloud analytics server 104 may be reduced. As illustrated by checkbox 612 of FIG. 6, the video editor 102 may select to push all query parameters to the mobile computing devices 106. In other embodiments, the video editor 102 may select a subset of the query parameters to be pushed to the mobile computing devices 106; for example, media clip format and resolution requirements.

Some time after transmitting the media query, in block 520 the video editor 102 receives query results from the cloud analytics server 104. The query results identify media clips generated by mobile computing devices 106 that satisfy the query parameters of the media query. The query results may be sorted in order of relevance, date created, or otherwise. In some embodiments, the query results may include a reference to matching media clips. In other embodiments, the query results may include the media data 144 for the matching media clips.

In some embodiments, in block 522, the video editor 102 may present the search results to the user through a user interface. The user may provide a selection indicating the desired media clip. For example, in some embodiments the video editor 102 may present a list of the top three to five search results, including thumbnails or other representations of the matching media clips, on the display 130 of the video editor 102. The user may be able to quickly select a desired clip from among the search results. In other embodiments, rather than presenting the search results to the user, the video editor 102 may automatically select a search result without further direction from the user, for example, the best-matching search result. The video editor 102 may determine whether or not to display the search results based on a selection from the user, for example, as illustrated by radio button group 610 of FIG. 6.

In block 524, the video editor 102 outputs the selected media clip into the associated dynamic content slot of the media program. As described above, the selected media clip may be selected by the user through a user interface, or may be selected automatically. In block 526, in some embodiments, the video editor 102 inserts the selected media clip into a video output generated based on the media program. The video editor 102 may render the video output to an output media file suitable for later playback. In some embodiments, the video editor 102 may render video output that is immediately or nearly immediately transmitted to a video device of a video consumer. For example, the video editor 102 may produce a live video stream that is broadcast over television, or streamed to video consumers over the network 108. After generating the video output, the method 500 loops back to block 502 to continue building media queries.

Referring now to FIG. 8, in use, the cloud analytics server 104 may execute a method 800 for receiving and processing media queries from the video editor 102. The method 800 begins with block 802, in which the cloud analytics server 104 determines whether a media query has been received from the video editor 102. If not, the method 800 loops back to continue waiting for media queries in block 802. If so, the method 800 advances to block 804.

In block 804, the cloud analytics server 104 parses the media query received from the video editor 102. The cloud analytics server 104 may interpret and evaluate each query parameter of the media query. In some embodiments, in block 806, the cloud analytics server 104 may analyze a sample media clip supplied with the media query. The cloud analytics server 104 may perform the same analysis on the sample media clip as is performed on media clips submitted by the mobile computing devices 106, as described below in connection with FIG. 9.

In some embodiments, in block 808, the cloud analytics server 104 may transmit query parameters of the media query to the mobile computing devices 106. For example, in some embodiments, the cloud analytics server 104 may maintain a list of mobile computing devices 106 and may push the query parameters to each. In some embodiments, the cloud analytics server 104 may store the query parameters and supply the query parameters to the mobile computing devices 106 when requested. Additionally, although illustrated as occurring in block 808, in other embodiments the cloud analytics server 104 may provide the query parameters to the mobile computing devices 106 at other times.

After some time, in block 810 the cloud analytics server 104 searches the media data 144 based on the media query. The cloud analytics server 104 may perform such search using the metadata 146, or by directly analyzing the media data 144. In some embodiments, in block 812, the cloud analytics server 104 searches the media data 144 based on metadata query parameters of the media query. For example, as described above in connection with FIG. 5, metadata query parameters may include search keywords, plaintext description, technical metadata attributes, a sentiment factor, location, or date and time. In some embodiments, in block 814, the cloud analytics server 104 searches the media data 144 based on media query parameters. For example, as described above in connection with FIG. 5, the media query parameters may be based on focus, stability, lighting or exposure, audio, or motion of the media data 144 itself. In some embodiments, in block 816, the cloud analytics server 104 searches the media data 144 based on sample media query parameters. For example, as described above in connection with FIG. 5, the sample media query parameters may include a sample media clip and matching options based on facial recognition, object recognition, text recognition, color balance, color saturation, or audio tune.

After searching the media data 144, in block 818, the cloud analytics server 104 ranks and sorts the search results. The cloud analytics server 104 may rank the search results based on the best match to the media query, the date of the media clip, or any other ranking criteria. In block 820, the cloud analytics server 104 transmits the search results to the video editor 102. In some embodiments, the cloud analytics server 104 may send a list of top-ranked search results. In other embodiments, the cloud analytics server 104 may send a single search result. In some embodiments, in block 822 the cloud analytics server 104 transmits the media data 144 of a selected media clip. As described above in connection with FIG. 5, the selected media clip may be the single top-ranked media clip, or may be a media clip selected by the user of the video editor 102. After transmitting the search results, the method 800 loops back to block 802 to continue waiting for additional media queries.

Referring now to FIG. 9, in use, the cloud analytics server 104 may execute a method 900 for receiving and processing media clips from the mobile computing devices 106. The method 900 begins with block 902, in which the cloud analytics server 104 determines whether a media clip upload has been received from a mobile computing device 106. If not, the method 900 loops back to continue waiting for media clip uploads in block 902. If so, the method 900 advances to block 904.

In some embodiments, in block 904, the cloud analytics server 104 pre-processes media data 144 received from a mobile computing device 106. In some embodiments, such pre-processing may be embodied as any analysis or evaluation of the media data that may be performed quickly and without using excessive compute resources 140. For example, pre-processing may be embodied as evaluating metadata 146 or format data associated with the media data 144. In such example, the cloud analytics server 104 may evaluate a source location associated with the media data 144, a media format of the media data 144, or a resolution of the media data 144. In other embodiments, pre-processing may include evaluating capabilities of the mobile computing device 106. For example, the cloud analytics server 104 may evaluate the processing capabilities or available network bandwidth of the mobile computing device 106. Information on capabilities of the mobile computing device 106 may be received with the media data 144, as described below in connection with FIG. 10.

In block 906, the cloud analytics server 104 determines whether to reject the uploaded media data 144. The cloud analytics server 104 may reject the media data 144 based on the results of the pre-processing of block 904. Criteria for rejection may be based on one or more media queries that have been received from the video editor 102. For example, the cloud analytics server 104 may reject media data 144 that is not from a particular source location, that is supplied in an incorrect format, or that does not have a required resolution. In some embodiments, the cloud analytics server 104 may reject media data 144 from mobile computing devices 106 that do not have desired capabilities; for example, mobile computing devices 106 with insufficient processing power or network bandwidth. Rejecting media data 144 prior to extensive processing may conserve compute resources 140 and/or reduce the amount of media data 144 and metadata 146 that must be stored in the storage resources 142. If the cloud analytics server 104 determines to reject the media data 144, the method 900 loops back to block 902 to continue waiting for media uploads. If the cloud analytics server 104 determines not to reject the media data 144, the method 900 advances to block 908.

In block 908, the cloud analytics server 104 post-processes the uploaded media data 144. Post-processing may include computing-resource-intensive calculations performed on the media data 144. Such post-processing may be scheduled or distributed among the compute resources 140 of the cloud analytics server 104. Results of post-processing may be indexed or stored in the metadata 146, to improve search performance In some embodiments, in block 910 the cloud analytics server 104 processes video image content of the uploaded media data 144. That image analysis may be used to evaluate query parameters received from the video editor 102. For example, the cloud analytics server 104 may analyze the media clip to determine whether it is in focus, determine whether the camera is stable, determine lighting or exposure information, or determine whether the media clip includes motion. The cloud analytics server 104 may further perform facial detection analysis, object detection analysis, optical character recognition and other text recognition analysis, and analysis of image color and saturation. In some embodiments, in block 912, the cloud analytics server 104 analyzes the audio content of the uploaded media data 144. Again, that audio analysis may be used to evaluate query parameters received from the video editor 102. For example, the cloud analytics server 104 may determine whether the media data 144 includes audio information, and may perform audio tune analysis of the media data 144. Audio tune analysis may include identifying musical tones in the audio data as well as determining how closely the audio data matches a musical tone. In some embodiments, in block 914, the cloud analytics server 104 may process metadata 146 embedded in the uploaded media data 144. That metadata analysis may be used to evaluate query parameters. For example, the cloud analytics server 104 may evaluate location coordinates embedded in the media data 144 or may evaluate technical attributes of the recording device that are embedded in the media data 144.

In block 916, the cloud analytics server 104 determines whether to reject the uploaded media data 144. The cloud analytics server 104 may reject the media data 144 based on the results of the post-processing of block 916, as well as any result from pre-processing of block 904. As described above in connection with block 906, criteria for rejection may be based on one or more media queries that have been received from the video editor 102. The uploaded media data 144 may be rejected after post-processing to store only media data 144 that satisfies a media query, or to prevent storage of cumulative media data 144. If the cloud analytics server 104 determines to reject the media data 144, the method 900 loops back to block 902 to continue waiting for additional uploaded media data 144. If the cloud analytics server 104 determines not to reject the media data 144, the method 900 advances to block 918.

In block 918, the cloud analytics server 104 stores the uploaded media data 144. As described above in connection with FIG. 5, storage resources 142 for the media data 144 may be pre-allocated based on a scheduled date and location of a media query. For example, storage resources 142 may be located in a datacenter geographically close to a scheduled live event. In some embodiments, in block 920 the cloud analytics server 104 stores a media retention policy associated with the media data 144. The media retention policy may dictate how long the media data 144 is stored and when the media data 144 is deleted. For example, the media retention policy may dictate that the media data 144 be deleted some time after the scheduled date of a media query. Thus, the media retention policy may conserve storage resources 142 of the cloud analytics server 104. In block 922, the cloud analytics server 104 stores metadata 146 associated with the uploaded media data 144. As described above, the metadata 146 may be searched to return associated media data 144 as a search result to the video editor 102. After storing the media data 144 and the metadata 146, the method 900 loops back to 902 to continue waiting for uploaded media data 144.

Referring now to FIG. 10, in use, a mobile computing device 106 may execute a method 1000 for capturing media clips and uploading the media clips to the cloud analytics server 104. The method 1000 begins with block 1002, in which the mobile computing device 106 requests query parameters from the cloud analytics server 104. The query parameters derive from the media query produced by the video editor 102. The received query parameters thus represent an acceptance policy describing media data 144 that could be provided to the video editor 102. Although illustrated as requesting the query parameters from the cloud analytics server 104, in some embodiments, the cloud analytics server 104 may push query parameters to the mobile computing device 106 without a request. In some embodiments, in block 1004, the mobile computing device 106 may transmit capabilities information to the cloud analytics server 104. As described above, the capabilities information may include information describing the processing capability of the mobile computing device 106 or concerning available network bandwidth.

In block 1006, the mobile computing device 106 determines whether query parameters have been received from the cloud analytics server 104. If not, the method 1000 advances to block 1012, as described below. If so, the method 1000 branches to block 1008.

In block 1008, the mobile computing device 106 configures media capture settings based on the query parameters. By configuring capture settings, the mobile computing device 106 may ensure that captured media data 144 is usable by the video editor 102 prior to capturing. For example, the mobile computing device 106 may configure media format, resolution, lighting, or exposure settings according to query parameters. Those query parameters are derived from the media query produced by the video editor 102.

In some embodiments, in block 1010 the mobile computing device 106 displays a media capture assistance user interface based on the query parameters. The media capture assistance user interface may be embodied as words or symbols displayed on the display 170 of the mobile computing device 106. For example, the mobile computing device 106 may display textual instructions based on the query parameters. Continuing that example, the query parameters may include a search for a person smiling and waving at the camera. In that example, the mobile computing device 106 may prompt the user to direct the subject to smile and wave at the camera. In another example, the query parameters may indicate that only in-focus, stable images will be accepted. In that example, the mobile computing device 106 may display text or symbols directing the user to correct focus or stability problems. After block 1010, the method 1000 advances to block 1012.

In block 1012, the mobile computing device 106 captures media data 144. The mobile computing device 106 may capture video clips, audio clips, still images, or any other media data 144. Media capture may be initiated by a user interface interaction or automatically without further direction from the user.

In block 1014, the mobile computing device 106 processes the captured media data 144. Processing may be minimal, such as converting the captured media data 144 to an appropriate file format, or involved, such as performing content analysis such as facial recognition, object detection, audio tune analysis, or the like. The extent of processing performed by the mobile computing device 106 may depend on the capabilities of the mobile computing device 106. In some embodiments, in block 1016 the mobile computing device 106 tags the captured media data 144 with metadata 146. The metadata 146 may include technical information identifying the mobile computing device 106 or providing capture information such as white balance, exposure, aperture, image quality attributes, or similar In some embodiments, the metadata 146 may include location information. For example, the metadata 146 may include GPS coordinates provided by the location circuitry 176.

In block 1018, the mobile computing device 106 determines whether to reject the captured media data 144. The mobile computing device 106 applies the received query parameters to the captured media data 144 to determine whether the acceptance policy of the video editor 102 has been satisfied. In many embodiments, no captured media data 144 will be rejected, because the media capture settings were correctly set in block 1008 based on the query parameters. In some embodiments, the media data 144 may be rejected based on processing performed in block 1016. For example, media data 144 may be rejected if facial recognition technology has not identified any faces in the captured media data 144. Rejection of media data 144 by the mobile computing device 106 may reduce demand on the compute resources 140 of the cloud analytics server 104. Of course, if no query parameters have been received by the mobile computing device 106, no captured media data 144 may be rejected. If the mobile computing device 106 determines to reject the captured media data 144, the method 1000 loops back to block 1002 to continue capturing media data 144. If the mobile computing device 106 determines not to reject the captured media data 144, the method 1000 advances to block 1020. In block 1020, the mobile computing device 106 uploads the captured media data 144 to the cloud analytics server 104. After upload, the method 1000 loops back to block 1002 to continue capturing media data 144.
